Today in mindblowing: Polish architects Irek Glowacki and Marek Rozhanski have built an upside-down house in Western Austria. Not only does the place look inverted from the outside—let's face it, that's nothing new—but all the contents (furnishings, lamps, rugs, accessories, rugs, kids' toys) are arranged in reverse. The floor's on the ceiling, the ceiling's on the floor, and so on. Obviously nobody actually lives in it—although could you imagine?—but rather the architectural marvel was designed as a tourist draw. Watch the video below.
